Conteúdo:  China Ball clay has been used for centuries in the tiling and pottery-ware industry. Because it is much finer than the other components in the casting slip the ball clay dominates the particle-particle interactions. Therefore, the ball-clays give the cast its plasticity and cohesion. The clay under investigation is a dark slightly sandy china ball (DSSCB) clay with a high content of finely divided kaolinite and is mixed with other substances for casting. Because of its surface area properties and its associated organic matter it has an important influence on the cohesiveness and visco-elastic properties of the clay bodies used in manufacturing pottery ware. The fine particles in the ball clays have an important influence on the rheology of the wholebody, and stabilise the flow and casting properties of the slip. A number of analytical procedures have been used in this study in order to gain a better understanding of the clays and their associated organic materials. Identification of the amount and nature of the active organic fraction and of its mode of action is important. The work described here is part of a larger project that investigates the chemical properties and compositions of the clay and lignite materials, and the nature of clay-humic complexes and of lignite materials in clay and lignite deposits.

Conteúdo:  Abstract: Goat breeding in the Northeast region of Brazil plays an important socioeconomic role. However, there are significant losses caused by sanitary deficits and infectious diseases, particularly caseous lymphadenitis (CL). Although CL is considered endemic in Northeastern Brazil, a comprehensive and up-to-date study of this disease in goat herds in this region is necessary. The objective of this study was to determine the farm-level and animal-level seroprevalences for the disease and to identify the possible risk factors that characterize CL in the caprine species of five Northeastern?s states (Ceará, Piauí, Rio Grande do Norte, Paraíba, and Sergipe). A total of 2744 goat serum samples from 230 farms were collected between 2010 and 2012. The diagnosis of Corynebacterium pseudotuberculosis infection was performed using the indirect ELISA technique. Farm-level and animallevel seroprevalences were 87.8% and 30.3%, respectively, suggesting that C. pseudotuberculosis is widespread in goat herds of the Northeast region. The risk factors were as follows: absence of forage silage (odds ratio = 5.39), not separating animals by sex (odds ratio = 4.16) or by age (odds ratio = 6.30), not replacing old goat breeders (odds ratio = 7.80), and non-treatment of CL lumps prior to spontaneous rupture (odds ratio = 10.34). This study supports the idea that caseous lymphadenitis is widely disseminated in goats from Northeastern Brazil and based on the risk factor analysis attention should... Mostrar Tudo
